BACK-REST.

, Specificationof Letters Patent.

Patented July 1,1919.

Application filed May 9, 1918. Serial N 0. 2335499.

To all whom it may concern: I 1 Be 1t known that I, ERNEST G. LrNoBLoM,

a citizen of Sweden, residing at Providence;

in the county of Providence and State of Ithode Island, have invented certain new and useful Improvements in Back-Rests, of which the following is a specification.

This invention has relation togback rests, and the nature and objects thereof will be readily apparent to those skilledin the art to which it appertains in the light of the following explanation of the accompanying drawings, illustrating what I now believe to be the preferred embodiment, or me chanical expression of my invention, from among other forms and arrangements within the spirit thereof or the scope of the appended claims.

However, an object of the invention is to provide a back rest of a portable nature designed to be erected upon the ground to support the back of a person sitting upon the ground, or reclining.

Another object of the invention is to provide a back rest of the character above set forth including a collapsible frame with means for stretching a strip of canvas taut when the same is in an extended position, and hingedly mounted props to retain the frame in an upright position.

I11 addition to the foregoing my invention comprehends improvements in the details of construction and arrangement of the correlative parts to be hereinafter more fully described and particularly set forth in the appended claims.

In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear;

Figure 1, is a view in front elevation of a back rest constructed in accordance with my invention.

Fig. 2, is a view thereof in side elevation, and, a

Fig. 3, is a view in front elevation of the props, illustrating the manner in which they are connected.

With reference to the drawings, 10 indicates generally a frame consisting of a pair of uprights 11 having their upper ends bent laterally as at 12 and formed with apertured ears 13 one pair of cars being formed on the upper end of each upright. Each upright is furthermore formed adjacent its 1 upper andlower end witheyeshlt, orsaid eyes may be removably connected thereto whereby the eyes may be connected together by means ofspacing member 15, a pairjof which posed eyes at the upper and lower ends of theuprights. The spacing members lo may be permanently connected to one set of eyes and formed with hook shaped members 16 at. their opposite endsqto releasably engage theother set of eyes whereby to permit the supports to be collapsed and tied together when desired. When the uprights are spaced apart by means of the members 15 t ey form a rectangular frame upon which a strip of canvas 17 or the like may be sup ported The marginal edges of the canvas being secured to the uprights by means of cord or the like 18. To theupper end of each upright 11 there is pivotally connected a prop 19, each prop being apertured at its upper end for insertion between the pairs of cars of the upright whereby the props may be extended downwardly in diverging relation to the supports as shown in Fig. 2. The props are each provided at points intermediate their ends with an eye 20, and said eyes are connected together by means of a spaced member 21 similar to the spaced members 15 similarly provided at one end with a hook shaped terminal 22 for releasable engagement in one of the eyes of the props.

Thus it will be seen that by disconnecting the spacing members 15 and 21 the props may be tied together as well as the uprights, and the-entire structure encompassed within a relatively small space. The strip of canvas 17 being secured to the uprights, it will be apparent that the props may be folded within the strip and the entire structure rolled up permitting transportation thereof in a convenient manner. At the place of use, the. supports are unfolded and spaced apart by members 15 and the props moved in diverging relation to the uprights as shown. in Fig. 2 whereupon the back rests may be utilized to form a support for the back of a person, sitting or reclining upon a lawn. Other uses and advantages of this device will be readily apparent.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and ar are provided for connection to op:

rangement and combination of parts, materials, dimensions, etc., as may prove expedient and fall within the scope of the appended claim.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is A backrest including a substantially rectangular frame member comprising parallel side bars, each provided at each end with an eye bolt, hook members swingingly connected to the eye bolt in one of the said side bars, and having their free ends provided with hooks adapted to engage the eye members on'the other side bar whereby the two side bars may be held in spaced relation when the backrest is in operative position,

a canvas covering having its marginal 1ongitudlnal edges fastened to the sald parallel bars whereby the said canvas covermg is ERNEST Gr. LINDBLOM.
